IMPROVEMENT IN CONDENSERS FOR SPELTER-RETORTS.

Specification forming part of Letters Patent No. 193,461, dated July 24,1877; application filed December 16, 1876.

To all whom it may concern Be it known that I, ERNsT H. RIoHTER, ofJersey City, in the county of Hudson and State of New Jersey, haveinvented a new and Improved Condenser for Spelter-Retorts, of which thefollowing is a specification:

Figure 1 is a longitudinal central section of my improved condenser.Fig. 2 is an inner end view of the same.

Similar letters of reference indicate corresponding parts in all thefigures.

This invention relates to an improvement of the truncated conicalcondensers that are applied to retorts of spelter-furnaces forcondensing the vaporous products of sublimation, and has for its objectto strengthen the inner end of the condenser, and also to prevent theentry into such condenser of matter foreign to the products ofsublimation to be gathered therein.

The invention consists in supplying the in; ner larger end of thecondenser with an annular bridge or bracing plate, through which thegases may enter the condenser, but which will preventthe fluid contentsof the retort from flowing into the condenser.

The letter A in the drawing, represents the condenser. The same is madeof the usual or suitable form, preferably of truncated conical shape,made of clay mixed with other ingredients, in the usual or in a suitablemanner,

and open at both ends. Its larger end is built into the retort in theusual manner, but is in this case strengthened by an inner annularbridge, B, which is made part of and in one piece with the condenser.Through the central opening in this bridge the vapors from the retortcan enter the condenser, but the bridge prevents the liquid matter inthe retort from flowing into the condenser, and prevents, also, thescraping by a poker or other tool usually employed of matter from theretort into the condenser. The bridge also serves to materiallystrengthen the inner end of the condenser, which is liable to breakageif not strengthened by such bridge or equivalent means.

By having the bridge of annular form-the condenser is in condition to besecured within the retort, with either side up, or, in other words, nocare need be taken to keep any particular part of the condenser at thetop, bot tom, or side.

I claim as my inventiona The condenser A, provided with the annularstrengthening-bridge B, substantially as and for the purpose hereinshown and described.
